Investigation of Hydraulic Conductivity of Soilcrete Specimens Made from Dredging Sand and Cement
The Soil Cement Mixing technology (SCM) has been widely applied for several applications such as soft ground improvement for highway embankments and earth levee embankments, seepage cutoff walls, and so on. The hydraulic conductivity of soilcrete made from clays was primarily studied. The hydraulic conductivity of soilcrete created from sand has limit research data, especially in Vietnam. This study aims at better understanding of the permeability behavior of dredging sand taken in Mekong delta mixing with some cement types at various cement contents of 200, 250, 300, 350 and 400 kg/m3, respectively. Three cement types of the ordinary Portland cement (OPC), Portland cement blended (PCB) and Portland cement slag (PCS) were utilized. All permeability tests followed the ASTM D5084 standard. The results indicate that the hydraulic conductivity of sand soilcrete (ks) was lower 1000 times than that of the compacted sand sample. The ks reduced with increasing in cement contents and in curing time. ks of soilcrete made from the PCS cement was lower than those made from the OPC and PCB cement. The ks varied from 8.07 × 10−8 m/s to 2.3 × 10−11 m/s.
